Median lobe plus median struts slightly curved, about 5.6 times as long as wide; median lobes 3.1 times as long as median struts; dorsal plate shorter than ventral plate, apex pointed. Internal sac with rod at apex, the rod approximately as long as median lobe plus median struts and slightly thick. 8th abdominal tergaum sub-trapezoidal, 0.6 times as long as wide; apex flat, narrower than base, with dense long setae on lateral sides, sparsely covered with short hairs at middle; 8th abdominal sternum approximately as wide as but shorter than
